6 FAQs about [Grinding the photovoltaic panel surface]

Can selective grinding remove resin from glass in silicon-based PV panels?

Selective grinding during the initial stage of grinding is effective for removing resin from glass in silicon-based PV panels. Many previous studies on the separation of glass from resin have investigated the applicability of chemical processes, but we achieved separation by brief physical processes.

How is selective grinding used to remove resin from glass particles?

Selective grinding was used to remove resin from glass particles as a secondary grinding process for the recycling of glass from silicon-based PV panels.

What is the difference between mechanical and thermal treatment of photovoltaic panels?

The mechanical methods include crushing, attrition, and vibration for glass separation and is the less polluting method compared to the other two [ 10, 11, 12 ]. Thermal treatment is mainly used to remove the polymeric fraction of the photovoltaic panel, i.e., EVA resin and backsheet materials [ 13, 14 ].

Can crystalline Si & Ag photovoltaic panels be recovered from end of life?

This work proposes an integrated process flowsheet for the recovery of pure crystalline Si and Ag from end of life (EoL) Si photovoltaic (PV) panels consisting of a primary thermal treatment, followed by downstream hydrometallurgical processes.

Can a PV panel be used as a raw material?

The selectivity was high at a high rotation speed and during the initial stage of grinding. We found that 97% of the glass in a PV panel can be recovered with less than 1% C contamination for particles smaller than 5.6 mm by grinding at 2500 rpm for 5 min. The resulting glass particles are suitable for use as raw material for glass fiber.

How to remove tempered glass from PV solar panels?

Immersing PV solar modules in hot water (80 °C) after aluminum frame removal resulted in easy removal of tempered glass from the assembly, followed by manual removal of busbars which comprises copper wire coated with tin. Removing glass particles before treatment prevents glass contamination in the silicon wafer powder. 3.
